systemd: write to RTC in utc. to keep in line with connman
libX11: fix non-working keyboard layouts (again)

   this is a partial solution. requires invocation of
   setxkbmap when a keyboard is added / replugged.
   a propper fix is to move xkb setup to udev. I will do
   that later when our new settings addon is ready.

   closes #108 #823 #1661 #1741 #1743
libX11: mostly cosmetics, we dont do install from $SYSROOT_PREFIX :-)
